Today, the status of gold mining

Gold dig is the declension of specious from the formation of princely-rich process. There area variety of techniques can be exploitd from the formation of the bullion, the most primitive federal agency is prosperous, then by and by Gold Separation Equipment Sieving. Currently on industrial multi- purified gold cyanide, scarce cyanide toxic, and therefore are developing new gold blood line reagents. Gold mining major ways open pit gold mining can be divided into two and underground mining to underground mining based.Suitable for open-pit mining in general and micro-fine gold placer mining. Placer gold mining has two mining and conventionalized gold mining ship, the former is used in eluvial zone and the presence of a large return of coarse gravel riverbed areas to dig for gold richer artificial apparent horizon for the purpose. General dug placer exists only in some small economic ore, ore human body of 0. 02 g / m3 can be more profitable.Some gold mining river boat is larger, more stable gold grade gold layer, artificial profits or difficult to dig a large gold mining company under the gold mining area to the way large-scale mining, gold mining ship costs are commonly up millions of dollars, and therefore requires a ood gold mining operation area. thermionic vacuum tube mining is the main way Chinese gold mining, because most of the Chinese gold deposit is concealed, semi-concealed orebody, requires the use of open hole ways to mine gold In South Africa, the worlds most advanced gold mining straight hole to a depth of 3,000 meters.Since gold buried fertile underground, sulphide mineral-based gold mining requires a higher ore grade, simple alternate minimum sulphide ore industry requirements in 2 grams / ton, mined at an average grade of 4 g / ton to profit . Depending on the complexity of he gold grade of ore types and optional other associated minerals whitethorn be, no useful elements of high muddy high arsenic sulfide gold ore is requ ired to reach a favorable 7-10 g / t mined before.As other major minerals associated minerals, such as zinc, copper associated grade often in one gram / ton, only in the character of other minerals as a companion to profitable mining. With the development of information and technology, gold mining equipment and Gold Separation Equipment are in aeonian innovation, I believe that one day in the near gold mining will become much easier.
